PolysacDB ID2490
Carbohydrate NameSsp-4 (amastigote surface glycoprotein)   (Drugpedia)
Carbohydrate ClassGlycoprotein
Microbe NameTrypanosoma cruzi amastigotes   (NCBI Taxonomy)   (Drugpedia)
Basic StructureSsp-4 is an amastigote-specific 84 KDa surface component defined by monoclonal antibody (MAb) 2C2, that was shown to be linked to the membrane by a GPI anchor. The epitope defined by MAb 2C2 is homogeneously distributed over the amastigote surface throughout the intracellular life cycle until it is gradually shed through a phospholipase-dependent mechanism during transformation into trypomastigote
BCSDB StructureN/A
Proposed FunctionN/A
Antigenic NatureMixtures of heat-inactivated intracellular and extracellular amastigotes
Carrier NameNil
Conjugate MethodNil
AntibodiesMab 1D9
Antibody Type ClassIgG3
Assay SystemELISA, immunoblotting, immuno-electron microscopy and confocal immunofluorescence
Cross ReactivityThis Mab cross-reacts with membrane of amastigotes from 569, 588, 573, 587 and SC2005 isolates, similar to the G isolate. It also reacts with the CL isolate
Proposed EpitopeN/A
IEDB EpitopeN/A
Proposed UtilityThis Mab reacted with cytoplasmic membrane-bound compartments of the amastigotes. This Mab specifically inhibited cell invasion by G and 588, but not CL strains
